    Who knows tires???

    Tire selection is limited these days on a stock 1983 GS1100E. LOL

    Any tire recommendations? I currently have Bridgestone Spitfire 130/90/17 rear and 100/90/19 front. The price was right and the worked well enough. A little more stick never hurts or could it?

    I’ve been told that modern sport tires would cause handling problems because they stick so hard they cause the weak frame/front forks of the GS to flex. How much damage could a pencil thin 130 do? Can you even find a sport compound in these sizes?


    I’ve also been told that as tires age they get hard from all the short trips where you heat up the tire. Even if they have many miles left for tread they may not perform as well as they should. Annual replacement is recommended. My tires are 5 years old. I’ve seen real old tires that have cracked and hardened but only after many many years. I’ve always replaced them. But annually? In the past before the kids and old age, my tires never made it to a year before needing to be replaced I rode all the time so this is the first time I've ever had to think about the tires age


    Input anyone?

    I just replaced my Spitfires with Battelax BT-45's in a V compound, when renobruce comes over tomorrow I'll be giving them the test! They should be a little better. Hopefully last as long.

      I have never heard the recommendation to do annual tire replacements, but that is what I do anyway.

      OK, so it's just over a year between tire changes, but it's just something that has to happen about every 20-23,000 miles.

        I have gotten up to 12,000 out of a rear Spitfire, more out of the front.
        Never got more than 5-6,000 out of Continentals or Dunlops.
        Something about that horsepower that makes them disappear.
        I do not buy touring tires. I ride "spirited."

            I would say the people that "told" you these things have a little bit of reading up and experiancing to do.

              Stick with the Spitfires I say.I've tried a few different types but keep coming back . They wear well , feel "planted" and have never felt "loose" in the wet. You can (at least I do ) get them cheaper through a car tyre dealer than anywhere else. Cheers,Simon.

                  Those sizes are correct.

                  The Avon AM26 RoadRiders are the most modern tires available, and they will transform the handling of this machine (in a good way -- it'll feel 100 pounds lighter). Highly recommended over the Bridgestone Spitfires, which are a very old design.

                  If you're doing track days or something, the Pirelli Sport Demons are also excellent, but they're softer and short-lived.


                  That stupid theory about not mounting up tires that are too sticky is just plain retarded. You want all the sticky you can get.

                    The guys at a local shop that I have been buying tires for the last 15 years tell me about the dangers of modern sport compound tires on a older bike. Funny thing is, same guys there the last 15 years.



                    Annual replacement came from advise a buddy of mine received from Freddy Spencer after he spent a day in his riding school.

                      That's the direction I'm going. but I want to see if anyone knew these "issues" had roots or not.

                        Annual replacement may be applicable for a track bike using race compound tires but a street driven GS is completely different.

                          That's actually not a bad idea, in a couple of ways. First, you need to ride more if your tires last more than half a season. Whaddya doing, sitting around watching TV? RIDE MORE, DAMMIT! It's good for your skills, your bike, and your mental health.

                          Secondly, I have noticed that tires definitely feel and grip differently with time and heat cycles, even if they're not worn. Even if I had a vast fleet of motorcycles, I would personally never stretch a set of tires beyond two years, even if they're not worn. Three years is generally considered OK, and five or six years is right out.

                            A valuable lesson learned from my weekend at the WV Rally. Don't install a Korean tire on the rear. I have a ChengSin on the back of one of my 1100s and a Kendra on the back of the other. Both felt greasy on even moderately damp roads. Either they're coming off my bikes or I will not ride on curvy wet roads with either bike.

                              pirelli sport demons are good..... like has been said they make the old girls feels a lot younger on their feet

                              combine that with the fact they're stickier, you'll be able to replace em sooner and not worry about old tyres on yer ride too

                              and freddie spencer.... what does he know anyway... lol - he was a honda rider
